.`GnuTLS` no longer rejects SHA-1-signed CAs if they are explicitly trusted
Previously, the `GnuTLS` library checked signature hash strength of all certificate authorities (CA) even if the CA was explicitly trusted. As a consequence, chains containing CAs signed with the SHA-1 algorithm were rejected with the error message `certificate's signature hash strength is unacceptable`. With this update, `GnuTLS` excludes trusted CAs from the signature hash strength checks and therefore no longer rejects certificate chains containing CAs even if they are signed using weak algorithms.
